To aZZ whom z't may concern:

Be it known that CHARLES Harmes WILLIAMS, a citizen of the UnitedStates, residing at city et Chicago, State of illinois, have invented 'acertain new and useful lmprovement in Third-Point Supports forBrake-Beams, of which theviollowing is a full, clear, and exactdescription, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in Which-Figure l is a side elevational view of a third point support for brakebeams, the same being applied to a beam. Fig. 2 is a detail vier.r ofthe support. Fig. 3 is a side elevational view of a modified form oi thesupport. Fig. i is a top plan view o'f the structure shown in Fig. 3.Fig. 5 is a side elevational View of another vform ot the strut. Fig. 6is a detail View shown in Fig. 5. Fig. 7 is a side elevational view ofanother modified form oi" the support. Fig. 8 is a detail view of theterm shown in Fig. 7. Fig. 9 is a detail view ot another modified formof the support.

This invention relates to a new and useful improvement in third pointsupports for brake beams such as disclosed in Patent No. 997,888 grantedto Charles H Williams, Jr., on July 11,1911.

It has been found in practice that the third pointsupport in the form ofa pivoted member arranged at the center of the brake beam at the end ofthe truss, and which pivoted member coperates with the inclined portionof the supporting track, will sometimes become accidentally displaced bybeing tilted back over the top of the strut and thereby impair theobject and purpose of .the third point support.

the present invention to provide means on the pivoted memberconstituting the third point support which will prevent this accidentaldisplacement.

' ln the drawings, in Figs. 1 and 2, I have shown conventionall3T thespring plank of a truck which is indicated at 1 and t0 which `is securedthe inclined track support 2. 3 is the head of a brake beam and e theusuai hanger thereof. 5 is the brake beam strut and 6 the tensionmember. 7 is the third point support pivoted at the outer end of thestrut between the two lugs constituting It is the purpose of oi thesupport.

contactfivith the nose lugs and prevent such tilting action.

in Figs. 3 and 4 l have shown the third point support as being providedWith two lugs 10, which serve to prevent the tilting action of the thirdpoint support, but like the construction shown in Fig. 1, these lugspermit a certain range of pivotal movement of said third point support..it is preferable to employ two lugs rather than one,

because by sodoing it is unnecessary to eX- erclse care in the exactarrangement of the third point support between the nose lues.

. i 5 and t3, lr have shown another form of my invention in the natureof extensions er horn-like proiections 11 which inclined upwardlj,7 away'from the track support so as 'not to add to the friction of themovement o,the third point support. These horn-like projections will,under ordinary service conditions, prevent any excessivetilting actionof the third point support.

ln Figs. .7 and 8, l have shown another modified construction designedparticularly for use in connection `-with brake beams in which thirdpoint support is pivotalljv mounted on the strut underneath instead ofdirectly in advance of the tension member. as shown in 1, 3 and 5. inthis modified form shown in Figs. Z and 8, the lugs 11, which restrainexcessive tilting action, are substantially T-shaped and are designed tocontact with the nose lugs in the event that the third point supportattempts to assume an abnormal position. ln Fig. 9 the lugs 12 aresubstantially the same as shown in Figs. and d except that they are not"if'shaped 'in the patent to idf. l. iiesei, dr., No. 997,992, datedJuly 1l, 191.1,.there is shown a third point support provided with lipswhich embrace the inclined track, but in order to remove the truck beamfrom the truck, it is necessary by this construction l dated May 2,1911,'tiieie is'shown a third .point support which embraces theinclinedtrack,- the llatter being reolded to avoid the objection mentioned withrespect to the liie-l sel patent. The'adi'antage of the Le Beau"-construction,however, only obtains with respect/to outside hung beams,and where the beams are inside hung, especially in trucks with narrowwheel bases,r the. Le Beau con.-

structlon possesses thel dlsadvantage of the Kiesel construction inthatl it' is necessary to remove the inclined track support in order toanhang the beam and move it from the tiucln The present improvement isto enable the dismantling'or unlianging of the beam in all classes oftrucks, regardless of whether or not the beam is inside or outside hung,yand at the same time provide means whereby any portion of the thirdpoint support will be prevented from ride ing the strut and tb' Lsbecoming vinoperative for the purposes for which it is intended.,v
